Good idea to define the bit offsets k3-pinctrl.h instead of magic numbers
here :)

Yup, and having that happen is enough to show the wake-up reason with
grep wakeup /proc/interrupts :)

The lack of bits at least earlier just meant that attempting to use a
wake-up interrupt would just never trigger. Worth checking though.
Dhruva, care to check if some padconf register have reserved bits for
29 and 30 that might be set high by default?
